Biofuels can provide energy without the reliance on environmentally harmful fossils fuels, but scientists are still searching for a plentiful source. Craig A. Kohn demonstrates how cellulose, the naturally abundant tough walls of plant...

Will using agrofuel offer a substantial alternative to using fossil fuel? With this experiment you can compare the amount of heat energy released by agrofuel and fossil fuel. The Science Buddies project ideas are set up consistently...

[Free Registration/Login may be required to access all resource tools.] Understand what trophic levels are and identify producers and consumers in a food web.

Students use real-world data to evaluate various renewable energy sources and the feasibility of implementing these sources. Working in small groups, students use data from the Renewable Energy Living Lab to describe and understand the...

Students analyze real-world data for five types of renewable energy, as found on the online Renewable Energy Living Lab. They identify the best and worst locations for production of each form of renewable energy, and then make...

Students become familiar with the online Renewable Energy Living Lab interface and access its real-world solar energy data to evaluate the potential for solar generation in various U.S. locations. They become familiar with where the most...

The object of this WebQuest is for you to research alternative fuels and figure out their benefits. Resources are provided as well as study questions to guide your quest.

This interactive Lab investigates what energy is, how it can be converted into useful forms, and why some sources are running low. The Research Challenge allows students to design their own renewable energy systems to generate power in...

After learning about all the energy sources, learners will be able to list and identify the economic and environmental advantages and disadvantages of them.

Students will use real satellite data to determine where the greatest concentrations of aerosols are located during the course of a year in the tropical Atlantic region and their source of origin.

With an introduction to the ideas of energy, learners discuss specific types of energy and the practical sources of energy. Hands-on activities help them identify types of energy in their surroundings and enhance their understanding of...

A comprehensive source of information about energy in all its forms. Each type of energy is explained, along with information about its environmental impact, supported with graphs, charts, and other data. There is a twenty-question quiz...

Promoting responsible energy choices and environmentally conscious government policies, NNEC provides information on energy and agriculture, the nexus of energy and water, complexities of power plants, natural gas fracking, energy...

Complete illustrated discussion of energy flow within ecosystems, including discussions of trophic levels, ecological pyramids, food chains and webs, biological magnification, and cycles.

Try this five question comprehension check over ecosystems and the ecological relationships within them.

Learn about the many different energy resources available from our Earth. Find out the pros and cons of each type: both renewable and nonrenewable.

This lesson will introduce energy pyramids, and show how energy moves from one trophic level to the next. It is 2 of 4 in the series titled "Energy Pyramids."

Students explore what kind and how much bio-mass can be produced in an area around your city or town. They figure how many gallons of fuel can be expected from one acre of crop land, and how much carbon can be sequestered in the local area.
